Benefits of technology

[0012]According to another aspect of the present invention there is provided an element of a device for forming an anastomosis, which element comprises a hollow sheath, and an elongate carrier member passing through the hollow sheath, with a portion of the sheath being attached to the carrier member and the remainder of the sheath being free to move lengthwise with respect to the carrier member, whereby such lengthwise movement causes the sheath to bulge outwardly. Preferably the sheath is a braided sheath, and more preferably it is a braided sheath of a surg

Problems solved by technology

Hand sewn anastomoses, usually in two or even three layers, are widely performed but are time consuming and require large incisions for hand access.

Embodiment Construction

[0028]Turning first to FIG. 8 of the drawings, it will be seen that this shows part of the gastrointestinal tract, and illustrates a tumour in the upper portion of the small bowel and the site at which it is desired to form an anastomosis to bypass the section of small bowel containing the tumour and thus permit its removal. What will now be described is the use of the embodiment shown in FIGS. 1, 1a, 1b and 2, in conjunction with some known pieces of surgical equipment, to form the anastomosis.

[0029]Although there are a number of alternative ways in which the surgical procedure can be carried out, one of them involves the following steps. Firstly a conventional flexible endoscope is passed through the mouth of the patient and thence through the patient's stomach and out through the pylorus into the small bowel. The leading end of the endoscope is passed at least as far as the site of the tumour. If the tumour is small enough it may be possible for the leading end of the endoscope t...

Abstract

A surgical device is provided for use in joining a first tissue layer forming a first hollow region and a second tissue layer forming a wall of a second hollow region, to produce an anastomosis. The device comprises a needle capable of passing from the first region to the second region by penetrating the tissue layers, a tag removably carried by the needle, the tag having a trailing portion, and means for separating the tag from the needle after the needle has penetrated both layers, to leave the tag in the second hollow region, but with the trailing portion extending into the first hollow region. Anastomosis forming articles are described which comprise a pair of components for compressing the tissue layers between them.

Description

[0001]The present patent application is a non-provisional application of International Application No. PCT / GB02 / 01268, filed May 20, 2002.FIELD OF THE INVENTION[0002]This invention relates to methods and devices for transfixing and joining tissues and, more particularly, to forming anastomoses.BACKGROUND OF THE INVENTION[0003]In abdominal and vascular surgery anastomosis, the joining together of hollow structures, is an important goal. The ability to establish continuity between two hollow structures can relieve blockage due to cancer, inflammation or other pathology, can allow the removal of abnormal tissue or organs, and, by bypassing a blocked segment, can allow the unimpeded movement of food or facilitate the flow of blood or bile through the body.[0004]Anastomoses are most commonly formed at open abdominal surgery (laparotomy). Hand sewn anastomoses, usually in two or even three layers, are widely performed but are time consuming and require large incisions for hand access. Sta...
